Getting error from subprocess module

[swechsler]

I'm writing a script to log disk usage on all our hosts to a central DB server. This works fine on one host, but on a different host I'm getting an error:

Output:

Both hosts are running CentOS 7 and Python 3.6.8

Doing a little more investigation, I was able to replicate the problem on the first host by running pip3 install subprocess.run. I then ran pip3 uninstall subprocess.run on both hosts and was able to get things working again.

I was unaware that Python includes the subprocess.run module, but apparently the version installed with Pip is faulty? Can someone explain what happened here?

It seems that there is a package named subprocess.run in pypi. It's probably not what you want. From your error message this package doesn't support a list as the first argument of run().

subprocess added the run() function in 3.5,not related to the 3-party PyPi module.

The run() function was added in Python 3.5;
